f IMPROVEMENT l-N JOURNAL-BQXES.

. The Schedule referredv to in these Patent part of the same.

To all lwhom. 'it may concern:-

Beit knownrthat I, JOHN SCHIEDER, of the city, county, and State of NewYork, have inventeda new and useful Improvement in Journal-Boxes; and Ido hereby declare the following to be a fu'll, clear, and exactdescription thereof, which will enable -those skilled in the art to makeaud use the same, reference being had to'the accompanying drawingforming part v.Figure 1 represents a transverse section of thisinvention, the line a; 2:, ig.- 3, indicating the plane of section. Y

Figure 2 is an end view of the same. A Figure .3 is a longitudinalcentral section o f the' same, the plane of section being indicated bythe line 'yr/a 1 Figure 4 is arv sectional fronti-'ieu' of the`box when'applied to a hanger.

Similar letters indicate corrcspomling parts.

This invention consists in a journal-box which contains twoadjnstableshells filled with bearingsurfaces composed of alternatelayers of Indiaa'ubber cloth and of sheet metal, sheet-copper being usedby'preference, in such a manner that a bearing-surface is obrenewed, andwhich can be easily adjusted by means of set-screws 4acting on theshells. f

The ends or heads of the box are removable, so that easy access-cau behad to the shells, and to each of said heads is secured a latch, whichserves to sup portthe shaft in case the lower shelleshould be re- Thejournal-box, when used in connectiou'with a hanger, is secured theretoby means of a swivel-arm, which swings on a pivot secured in the hanger,and

screws with right-and-let-hand screw-threads, in such a manner that thejournal-box can accommodate itself to the shaft passing through it, andthat the nuts on the screws with the right-and-left-hand threads are notliable to work loose spontaneously.

In the drawing- A designates a journal-box, each half of 'which isprovided with a shell, B.

These shells are exposed to the action of' set-screws a b c, bearingthereon from three sides, so that the same can be readily adjusted tothe correct position after thevbox is secured in its place.

Said shells are fitted with bearing surfaces zZ, coinposed of alternatelayers of India-rubber c-lothl and sheet metal, sheet-copper being usedby preference, and these layers are united by rivets e passing throughthem, as shown in g. 3.

By these means bearing 'surfaces are obtained which areself-lubricating, which are very durable, and whi'ci` work withcomparatively little friction.

' 'It' either' of said bearingsu'rfaces should wear off,

it can be readily brought in the required position by means of theset-screws a b c, and if the same should wear out it can beeasilyremovedand replacediby a new one. Y

In order to enable the workmen to effect this purpose, the heads f f ofthe box A are made removable,

being `s'ecuredin vposition by screws g.

To the outei:` surfaces of the lower heads f are secured the latchesTg'which, when the journal-box is in operation, are turned down tothevpositio'n shown in fig. 2; 'but if the bearing surfaces in the lowershells have to .be removed, one of the lower heads is nnscrewed and.taken off, and the latch on the opposite -head is turned up and securedin position, so as to support the shaft` while the shell is taken out.

For the purpose of securing the latches in this lastnandpositiomI haveprovided them with screws fi, which cau'be screwed into holes j, (see g.2.)

If my boi; is to be used on a'hanger, C, I provide the vsame with anarm, It, which is attached tol the hanger by means of a screw, l, sothat the box can accommodate itself to the shaft passing through it.

In the'a'rin k are two segmental slots,'m, (see tig.`

4,) and` through these slots pass screws `ln, with nuts o, andright-hand threads on one andleft-hand threads on the opposite ends.

'If the boi: should swing Aou its pivot Z, therefore, and if eitherofthe screws n `should turn,.having. a tendency to unscrewthe nut on oneof its ends, the nut on the opposite, end will screw up, and the boxwould become tight, or at least prevented from getting loosespontaneously.

What I claim as new, and-desire to secure by Lett-ers Patent, is'- 4 1.A journal-box, containing two shells, provided with bearing-surfacesmade of alternate layers ofIndiarubber cloth and sheet'metal,(sheet-copper being used vby preference',) said shells being adj ustedby means of set-screws so that the bearing-surfaces can be brought inthe required position, as herein shown and'described.

.2. The supporting-latches at the heads of the journal-box, providedwith `removable shells, substantially as set forth.

3. rIhe swivel-arm, securedto a hanger by-screws with right-and-left-hand threads, substantially as .l

herein shown and described.
